RELATED APPLICATIONS

The present application claims priority from Japanese Application No.2017-077314, filed Apr. 10, 2017, the disclosure of which is herebyincorporated by reference herein in its entirety.

TECHNICAL FIELD

The present invention relates to a nose pad for eyeglasses which comesinto contact with the nose to support eyeglasses and eyeglasses providedwith the pad.

BACKGROUND ART

As an example of a frame of eyeglasses, there is known a frame comprisedof a front portion that holds lenses, and temples coupled to oppositeend portions of the front portion to be foldable via hinges, where thefront portion is provided with a pair of circular rims that holds rightand left lenses, a bridge that connects between inner edge portions ofboth the rims, pad arms extending from respective inner edge portions ofthe rims, and a nose pad attached to respective front ends of the padarms so as to enable a direction to be varied in a predetermined range.

In wearing eyeglasses, front ends of the temples are put on ears of auser, while the nose pad comes into contact with opposite sides of thenose, and the eyeglasses are supported. Further, since the variety ofthe size and shape of the nose of a wearer is wide, the pad arms areformed to be deformable, and by permitting backlash of the direction ofthe nose pad at the front end of the pad arm, the eyeglasses are adaptedto the shape of the nose.

In addition, the present application includes “eyeglasses” and binocularloupes used in medical care and the like, as well as normal“eyeglasses”, and these are collectively called “eyeglasses”.

Since such a nose pad is a portion to support weights of the eyeglassframe and lenses, a corner of the outer edge portion of the nose pad andthe like bite into the nose, and in using for a long time, an imprintand/or pain sometimes occurs.

Particularly, in general nose pads, a surface opposed to the side faceof the nose is in the shape of a plane, while the side face of the nosenear the root of the nose that is brought into contact with the nose padis in a gentle concave shape, the side edge portion of the nose pad digsto make an imprint and/or cause pain easily, and there are requirementsto alleviate the imprint and pain. Further, it is also required to makethe eyeglasses hard to slip down.

Therefore, it is often performed that the nose pad is formed of softmaterials made of silicone resin so as to alleviate pain and prevent theeyeglasses from slipping down. Further, proposed are a nose pad to makean imprint hard to remain and alleviate pain by providing cushioningproperties and increasing an area of contact with the side face of thenose to disperse pressure as described in Patent Document 1, a pad thatis made of soft materials provided with at least one of adsorptionproperties and permeability to prevent makeup or eyeglasses from beingremoved or slipping down and that is attached to the nose pad portion ofthe eyeglasses as described in Patent Document 2, a silicone rubber sealthat is provided with a bump band on the surface of the pad coming intocontact with the nose to prevent slipping down and that is bonded to thenose pad portion of eyeglasses as described in Patent Document 3, andthe like.

DISCLOSURE OF INVENTION Problems to be Solved by the Invention

The eyeglasses provided with the nose pad as described in PatentDocuments 1 to 3 have certain effects on alleviation of the imprint leftafter wearing and pain, removal of makeup and slipping down of theeyeglasses. However, the nose pad as described in Patent Document 1 islarge in the contact area, and thereby enables the left imprint and painto be alleviated, but the effect is not sufficient. Further, the nosepads as described in Patent Documents 2 and 3 have an effect on slippingdown of the eyeglasses, but are not matched with the shape of thesurface of the nose. Further, since the pad locally contacts to increasepressure, there is a possibility that an imprint is left and/or painoccurs by wearing the eyeglasses for a long time. Furthermore, since thepad is bonded to the nose pad portion of the eyeglasses, there is apossibility that the pad peels off from the nose pad portionunintentionally and drops off.

Accordingly, the present invention is to solve the problems existing inconventional techniques, and to provide a nose pad capable of reducingan imprint after wearing eyeglasses, and pain and a feeling ofstrangeness in wearing and effectively preventing the eyeglasses fromslipping down, without worrying that the pad drops off from theeyeglasses unintentionally.

Means for Solving the Problem

In view of the above-mentioned object, the present invention is toprovide a nose pad which is attached to eyeglasses or binocular loupes,comes into contact with the nose to support the eyeglasses, and which isprovided with a base portion that is formed of an elastomer material andthat includes two contact surfaces coming into contact with the nose,attachment portions that are formed of a resin material and that areconnected to pad arms extending from the eyeglasses on the backside sideof two contact surfaces of the base portion, and bump portions that areformed of an elastomer material and that are provided at opposite endportions of the two contact surfaces to rise, where each of the bumpportions includes a curved convex surface, the resin material of theattachment portions is harder than the elastomer material of the baseportion and the elastomer material of the bump portions, and the convexsurface is provided with fine concavo-convex or linear embossingprocessing to increase an area of contact with the skin of the nose andprevent slippage.

It is possible to attach the above-mentioned nose pad to pad arms ofeyeglasses with the attachment portions, and therefore, the pad does notdrop off from the nose pad portion unintentionally, unlike a seal typenose pad.

Further, since the base portion is formed of the elastomer material andthe attachment portion is formed of the resin material harder than theelastomer material, the base portion is flexible to facilitateattachment to the pad arms of the eyeglasses, the attachment portion hasdurability, and it is also possible to prevent the elastomer portionfrom discoloring, which occurs due to generation of rust in the case ofusing metal in an attachment portion.

Furthermore, since the nose pad is provided at its opposite end portionswith the attachment portions, when the attachment portions are attachedto the pad arms extending from the eyeglasses, not only the opposite endportions of the nose pad come into contact with side faces of the nose,but also the intermediate portion between the opposite end portionscomes into contact with a part near the root of the nose. By this means,since the area of contact with the nose is increased to dispersepressure, a left imprint and pain occurs hard, and the eyeglasses arehard to slip down.

Still furthermore, the bump portions with curved convex surfaces areprovided on the surface contacting the attachment portions at theopposite end portions of the nose pad and the nose to come into contacttherewith, the pad is apt to adapt to the gently dented shape of theside faces of the nose near the root of the nose, and therefore, theeyeglasses are hard to slip down. Moreover, since the pad does not haveany corners not to bite into the nose, pain is hard to occur.

In addition thereto, the bump portions are provided, the curved convexsurface is provided with fine concavo-convex or linear embossingprocessing to increase the area of contact with the skin of the nose andprevent slippage, it is thereby possible to form a fine gap between thebase portion and the side face of the nose, and therefore, it is alsopossible to restrain the skin from getting humid and to reduce removalof makeup in the side faces of the nose. Further, since the base portionand bump portions coming into contact with the nose are formed ofelastomer materials, texture is good, and slipping is hard to occur.

In the above-mentioned nose pad, although it is preferable that the baseportion has the shape of a horseshoe, the base portion may be comprisedof two independent right and left bases.

In this case, it is further preferable that the opposite end portions ofthe base portion provided with the attachment portions and the bumpportions are thicker than the intermediate portion positioned betweenthe opposite end portions. By this means, since it is possible to formthe intermediate portion to be thin, it is made easier to hide theintermediate portion behind the bridge connecting between rims of theeyeglasses, and it is possible to make the appearance hard to impair.

As one Embodiment, the attachment portions and the bump portions areformed as members different from the base portion, and the bump portionsare engaged in the base member. In addition, in the present application,“engage” means that welding, adhesion, bonding or adherence is performedby chemical, thermal or mechanical technique.

The elastomer material of the base portion and the bump portions is oneof silicone rubber, urethane rubber, fluororubber, acrylic rubber,ethylene propylene rubber and polyisoprene rubber materials.

Further, as another aspect, the present invention is to provideeyeglasses provided with a front portion that holds lenses, templescoupled to outer edge portions of the front portion to be foldable, apair of pad arms extending from the front portion, and a nose padattached to the pair of pad arms, where the above-mentioned nose pad isused as the nose pad, and each fix portion of the nose pad is attachedto each pad arm.

In the above-mentioned eyeglasses, the front portion includes a pair ofcircular rims that hold lenses, and a bridge that connects between inneredge portions of the pair of rims, and it is made possible that the pairof pad arms extend from the inner edge portions of the rims or thebridge.

Further, in the above-mentioned eyeglasses, it is preferable that abox-shaped storage portion with a through hole formed is provided at thefront end of the pad arm, a through hole is formed in the attachmentportion, and that in a state in which the attachment portion is storedin the box-shaped storage portion, by passing a retaining screw throughthe through hole of the attachment portion and the through hole of thebox-shaped storage portion, the attachment portion is attached to thebox-shaped storage portion swingably.

Advantageous Effect of the Invention

According to the nose pad of the present invention and eyeglasses usingthe pad, since the nose pad is attached to pad arms of the eyeglassesvia the attachment portions, the pad is free from risk of dropping offfrom the eyeglasses unintentionally. Further, the portion coming intocontact with the face is formed of the elastomer material, the area ofcontact with the nose is large, and the bump portion is the curvedconvex surface without corners and adapts to a gentle dent in the sideface of the nose near the root of the nose. Therefore, pain isalleviated, and the eyeglasses are hard to slip down. Further, since thebump portion comes into contact with the side face of the nose, andforms a gap between the side face of the nose and the intermediateportion, it is hard to get humid, and it is also possible to suppressremoval of makeup.

In addition thereto, the curved convex surface in the bump portion ofthe nose pad is provided with fine concavo-convex or linear embossingprocessing to increase the area of contact with the skin of the nose andprevent slippage, it is thereby possible to form a fine gap between thebase portion and the side face of the nose, and therefore, it ispossible to suppress heating of the skin and accumulation of sweat, andto also reduce removal of makeup on the side face of the nose.

MODE FOR CARRYING OUT THE INVENTION

Embodiments of eyeglasses provided with a nose pad according to thepresent invention will be described below with reference to drawings.

First, referring to FIGS. 1 and 2, described is an entire configurationof the eyeglasses provided with the nose pad according to the presentinvention.

The eyeglasses 10 are provided with a front portion 12, and temples 16coupled to opposite end portions of the front portion 12 to be foldablevia hinges 14. The front portion 12 includes a pair of circular rims 20that hold right and left lenses 18, a bridge 22 that connects betweeninner edge portions of both of the rims 20, leg members i.e. pad arms 24extending from the rims 20 or bridge 22, and a nose pad 30 attached tofront ends of the pad arms 24 so as to enable a direction to be variedin a predetermined range, and the temple 16 is coupled to the outer edgeportion of each rim 20 to be foldable. In the Embodiment shown in thefigure, the pad arm 24 extends from near the center in the verticaldirection of the inner edge portion of the rim 20.

At the front end of the pad arm 24 is provided a box-shaped storageportion 26, and a through hole 26 a is formed in the storage portion 26.An attachment portion 34 of the nose pad 30 described later is stored inthe storage portion 26. By passing a retaining screw 28 through athrough hole 34 a provided in the attachment portion 34 of the nose pad30 and the through hole 26 a provided in the storage portion 26, theattachment portion 34 is attached to the storage portion 26 swingably.By this means, the attachment portion 34 is capable of varying thedirection in a predetermined range with respect to the pad arm 24,adapts the direction of a surface opposed to the nose of the nose pad 30to the side face of the nose having an individual difference to comeinto contact with the side face of the nose, and supports the frontportion 12 together with the temple 16. Further, the pad arm 24 isformed of a deformable material, and as shown in FIG. 2 in detail,preferably has a single or a plurality of curved portions. By thismeans, it is made possible to deform the pad arm 24 to adapt to shapesof various noses, and adjust the manner of contact between the nose pad30 and the nose.

Referring to FIGS. 3 to 7, described next is a detailed configuration ofthe nose pad 30. The nose pad 30 includes a horseshoe-shaped baseportion 32, attachment portions 34 protruding from the base portion 32to connect to the storage portions 26, and bump portions 36 raised fromthe base portion 32.

The base portion 32 is formed of a flexible elastomer material withelasticity, and has the horseshoe shape including two nose side faceopposed portions 32 a, 32 a extending approximately parallel, and anintermediate portion 32 b that connects between two nose side faceopposed portions 32 a, 32 a. As the elastomer material, for example, itis possible to use silicone rubber and the like. It is preferable thatthe intermediate portion 32 b is thinner in width than the nose sideface opposed portion 32 a. For example, in assuming that the width ofthe nose side face opposed portion 32 a is 8.3 mm, it is preferable thatthe width of the intermediate portion 32 b is 4.5 mm. By such aconfiguration, it is possible to deform the intermediate portion 32 beasier so as to curve to install in the pad arm 24 with ease. Further,the base portion 32 includes two flat frontside 38 a of the pad cominginto contact with the nose and backside 38 b thereof extendingapproximately parallel, and a curved connection surface 40 that connectsbetween the frontside 38 a and backside 38 b. The connection surface 40preferably extends in the shape of an arc. By connecting between twomain frontside 38 a and backside 38 b with the curved connection surface40, any corner is not formed, the pad is hard to bite into the nose, andsuch an effect is exhibited that pain occurs hard.

The bump portion 36 is formed of an elastomer material, and is providedto rise from the frontside 38 a at opposite end portions (end portionsof the side face opposed portion 32 a positioned on the side opposite tothe intermediate portion 32 b) in the longitudinal direction of the baseportion 32. It is preferable that the bump portion 36 is raised from thefrontside 38 a by a height about half the thickness of the base portion32. For example, when it is assumed that the thickness of the baseportion 32 is 2.5 mm, the bump portion 36 is preferably raised from thefrontside 38 a by 1.3 mm. The bump portion 36 is preferably formed ofthe same elastomer material as the base portion 32, and as the elastomermaterial, as in the base portion 32, for example, it is possible to useone of silicone rubber, urethane rubber, fluororubber, acrylic rubber,ethylene propylene rubber and polyisoprene rubber materials. Further,the bump portion 36 has a curved convex surface. In the Embodiment shownin the figure, the bump portion 36 is formed as a different member fromthe base portion 32, and is welded to the base portion 32, and it isalso possible to form the portion integrally with the base portion 32.

The attachment portion 34 is formed of a resin material harder than theelastomer material forming the base portion 32 and bump portion 36, andis provided to protrude from the backside 38 b of the pad surface 38coming into contact with the nose, at opposite end portions in thelongitudinal direction of the base portion 32. The attachment portion 34is preferably disposed on the intermediate portion 32 b side rather thanat the center of the bump portion 36. As the resin material, forexample, it is possible to use polyethylene, polypropylene and the like.Further, as shown in FIG. 7 specifically, the through hole 34 a isformed in the attachment portion 34, and by passing the retaining screw28 through the through hole 26 a of the storage portion 26 and thethrough hole 34 a of the attachment portion 34 in a state in which theattachment portion 34 is stored in the storage portion 26 provided atthe front end of the pad arm 24, it is possible to attach the nose pad30 to the front end of the pad arm 24 to be swingable in thepredetermined range. Accordingly, for convenience in attaching to thestorage portion 26, it is preferable that the attachment portion 34protrudes from the backside 38 b of the pad coming into contact with thenose by about 2.5 mm. In the Embodiment shown in the figure, theattachment portion 34 includes a disk-shaped foundation portion, and aprotrusion portion which protrudes and extends from the foundationportion, and in a state in which the protrusion portion is disposed in aconcave portion provided at the end portion of the base portion 32 toprotrude from the base portion 32, by welding the member constitutingthe bump portion 36 to the base portion 32 so as to cover an entrance ofthe concave portion, is attached to the base portion 32. However, it isalso possible to attach the attachment portion 34 to the base portion 32with an adhesive, or provide integrally with the base portion 32.

In using, the attachment portions 34 at opposite end portions of thenose pad 30 are stored in respective storage portions 26 of the pad arms24 so that the intermediate portion 32 b is disposed on the bridge 22side, and the nose pad 30 is attached to the pad arms 24. By this means,when a user wears the eyeglasses 10, the nose side face opposed portion32 a of the nose pad 30 is disposed to be opposed to the side face ofthe nose near the root of the nose of the user, at least a part of thenose side face opposed portion 32 a comes into contact with the sideface of the nose, and the intermediate portion 32 b of the nose pad 30is disposed to be opposed to the root of the nose and comes into contactso as to cover a part near the root of the nose. Thus, the pad comesinto contact with the nose not only in the side face of the nose, butalso in the part near the root of the nose, the area of contact betweenthe nose of the user and the nose pad is increased, pressure isdispersed, and therefore, pain due to wearing of the eyeglasses 10 for along time is alleviated, while the imprint is hard to remain. Further,in addition to that the portion coming into contact with the nose in thenose pad 30 is formed of the elastomer material hard to slide, when theintermediate portion 32 b comes into contact so as to cover the partnear the root of the nose and shifts in a drop direction, theintermediate portion 32 b is caught in the root of the nose, andtherefore, the pad also produces the effect that the eyeglasses 10 arehard to slip down.

Further, since the bump portion 36 and the attachment portion 34 areprovided at opposite end portions of the frontside 38 a coming intocontact with the nose and the backside 38 b of the base portion 32,respectively, when the attachment portion 34 of the nose pad 30 isstored in the storage portion 26 of the pad arm 24, and the nose pad 30is attached to the pad arm 24, the bump portion 36 is disposed on theside opposed to the side face of the nose, and in wearing the eyeglasses10, comes into contact with the side face in the vicinity of the root ofthe nose in the side face of the nose. While the side face in thevicinity of the root of the nose is a gentle concave shape, the bumpportion 36 coming into contact therewith has the curved convex shape,and therefore, is apt to adapt to the shape of the side face of the nosein a region with which the portion 36 comes into contact, and theeyeglasses 10 are hard to slip down. Further, since the bump portion 36that reliably comes into contact with the side face of the nose and theattachment portion 34 attached to the pad arm 24 are provided inpositions that are almost back-to-back at opposite end portions of thebase portion 32, the bump portions 36 are capable of reliably nippingside faces of the nose of the user, and the pad also exerts the effectof preventing slipping down.

Furthermore, since the bump portion 36 contacting the side face of thenose to come into contact therewith has the curved convex surface, andis hard to bite into the nose, pain is hard to occur, and the imprint isgenerated hard. In addition thereto, since the bump portion 36 is raisedfrom the base portion 32, when the bump portion 36 comes into contactwith the side face of the nose, a gap tends to be formed between theside face opposed portion and the side face of the nose, and it ispossible to decrease the area of contact between the side face opposedportion and the nose. By this means, it is possible to make a rashcaused by getting humid occur hard, and to reduce removal of makeup.

In addition thereto, as shown in FIGS. 8A to 8C, the curved convexsurface of the bump portion 36 is provided with fine concavo-convex,linear or wave line-shaped embossing processing to increase the area ofcontact with the skin of the nose and prevent slippage, it is therebypossible to form a fine gap between the base portion and the side faceof the nose, and therefore, it is possible to suppress heating of theskin, and to also reduce removal of makeup on the side face of the nose.FIG. 8A illustrates an example of fine concavo-convex embossing, FIG. 8Billustrates an example of linear embossing at fine intervals, and FIG.8C illustrates an example of cross line-shaped embossing at fineintervals.

By applying such fine particle-shaped, linear, wave line-shaped and/orcross line-shaped embossing processing to the curved convex surface ofthe bump portion 36 of the nose pad 30 according to the presentinvention, in the nose pad according to the invention, as well as thenon-slip effect by increase in frictional resistance between the nosepad and the skin of the nose, by preventing the nose pad from cominginto intimate contact with the skin, it is made possible to remarkablyincrease a wearing comfortable feeling of eyeglasses by suppressingsweating and further suppressing accumulation of sweat.

In addition, in the present application, “embossing processing” is notlimited to the processing as shown in FIGS. 8A to 8C, and inclusivelymeans all of any types of fine concavo-convex processing applied to thecurved convex surface of the bump portion 36.

In the above-mentioned Embodiment 1, the base portion 32 is configuredin the shape of a horseshoe, a pair of nose side face opposed portions32 a are continuously configured via the intermediate portion 32 b, andthe nose side face opposed portions 32 a of the base portion 32 may beconfigured independently in the right and left. FIG. 9 illustrates anose pad of the Embodiment 2 and eyeglasses. In the base portion 32, onthe backside side of the contact surface thereof, the attachment portion34, which does not appear in the figure, is stored in the storageportion 26, and Embodiment 2 is configured as in Embodiment 1 in therespect that by passing the retaining screw 28 through the through holesrespectively provided in the attachment portion 34 and the storageportion 26, the attachment portion 34 is attached to the storage portion26 swingably.

In the foregoing, the nose pad 30 according to the present invention andeyeglasses 10 provided with the pad are described with reference toEmbodiments 1 and 2 shown in the figures, but the invention is notlimited to the Embodiments shown in the figures. For example, in theEmbodiment shown in the figure, the pad arm 24 extends from the inneredge portion of the rim 20 of the eyeglasses 10, but the pad arm 24 mayextend from the bridge 22. Further, in the Embodiment, the nose pad 30according to the invention is attached to eyeglasses where the frontportion has a pair of rims, and it is also possible to attach the nosepad 30 according to the invention to eyeglasses where the bridge andtemples are directly connected to lenses without the rim, and the padarm extends from the bridge. Furthermore, the attachment portion 34 isconnected to the storage portion 26 at the front end of the pad arm 24by the retaining screw 28, and may be connected by another means.
